LASTING-MACI-IINE.

Application filed August 27 1910. Serial No. 579,263.

To all whom it may concern:

Be it known that I, MATTHIAs BROOK, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a spoolfication, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines of the bed type and has for its object to provide a machine having novel provisions for adjustment for right and left crooked lasts.

An advantageous characteristic of this invention is found in the saving of space vention by which the whole extent of adjustment required for a crooked last is divided Zbetween the two end lasting mechanisms which are displaced in opposite directions but only a short distance from the median and convenience of presentation of the shoe to the operator.

As pointed out in prior Letters Patent No. 1,018,477, granted Feb. 27, 1912 on my-application, the median lines of the foreparts and heel parts of crooked lasts are usually found to intersect in the forepart of the last and adjustment of the lasting mechanisms relatively to such point ofintersection is desirable in order to enable the heel and toe lasting mechanisms to operate symmetrically upon their respective ends of the shoe. In that patent is described a machine having important advantages which is arranged for adjustment of the heel lasting mechanism about a center located at the described point of intersection of said median lines.

One important feature of the present invention consists in mounting an end lasting mechanism for lateral curvilinear movement into different positions about a center which is located at a substantial distance in front of the toe end of the last for the purpose of adapting said mechanism to act similarly upon right and left crooked lasts. As herein shown the toe lasting mechanism isso mounted and the heel lasting mechanism is also laterally adjustable in a curvilinear ath.

p Various features of this invention relate to the relation of centers about which I have found that movement of the toe and the heel lasting mechanisms may be made with advantageous results. As I am advised, I am the first to provide a machine in which toe and heel lasting mechanisms I Specification of ljletters Patent.

Patented Dec. 2, 1913 fare each mounted for lateral curvilinear adjustments and each has its center of move :ment remote from either end of the shoe, as for example, centers located respectively 5m front of the toe and ofthe heel ends of the shoe, with or without connections for adjusting said mechanisms together in constant proportion or in proportions which fcan be varied for different styles of lasts. lt is new by this invention to provide a machine that has toe and heel lasting mech-' 1 an sms with means by which simultaneous iEtClJLlSlJIDBIltin predetermined different deg grees about two vertical axes having different relations to their respective ends ofthe last may be effected between the lasting mechanisms and the last.

The illustrated embodiment of this inline of the machine has the advantage that there is a minimum change of position of the lasting mechanisms relatively to the working position of the operator. He can therefore more conveniently carry on the lasting operation in the manner to which he is accustomed.

Another advantage is found in the economy of factory space required for each machine for obviously a less distance is permissible between machines the working positions of. which are confined between narrower limits.

I have found by careful experimentthat good results are obtained if the center of movement for the toe lasting mechanism is well in advance of the toe lasting plates, or wipers, for employment with lasts that have the large extent of swing in their forepart that characterizes those in use at the present time. Also the center of movement of the heel lasting mechanism for these lasts should, for the best results as I am now advised, be near the heel lasting plates and it may advantageously be located under the last in about the vertical plane of the heel breast.

By the illustrated connections it is practi selves. The centers of adjustment are preferably found in the carriages which support. the end lasting mechanisms and partake of such relative longitudinal adjustment as that of those carriages which is made for:

different lengths of lasts.

of my prior patents for example, in which toe and heel lasting wipers were adjusted angularly to face at an angle to the median line of themac'hine but were actuated in the median line of the machine rather than in the median lines of the adjacent ends of thelast.

These and other features of the invention, including certain details of construc- 7 tion and combinations of parts will be 'de scribed in connection with the specific embodiment thereof herewith .presented and will then be pointed out in the claims.

Figure 1 is a side elevation of a lasting machine embodying th'isinvention; Fig. 2 is a .plan with the toe and heel lasting mechanisms central of the machine; Fig. 3 is a plan showing the lasting mechanisms adjusted for a left last, the median lines of the machine and of the toe and heel portions of the last being indicated by diverging dotted lines in this figure; Fig. 4 is a detail.

The frame of the machine and the con-.

struction and arrangement of the toe and heel end lasting mechanisms may be the same as described in my prior application Serial No. 399,313, or any other suitable type of construction, except as may be here- It may be stated in geninafter specified. eral that the frame 2 of the machine supports a heel post and a toe rest, the latter of which may conveniently be arranged to slide transversely of the machine or have an extended shoe resting surface adapted to support a shoe with the median line of the last located over said rest at one side of the median line of the machine. The heel lasting mechanism4 is movable by a hand wheel 5 fromand toward the heel post to permit the removal and application of shoes to the post and the desired positioning of said lasting mechanism longitudinally with relation to the heel portion of the shoe. The toe lasting mechanism 6 is carried by a treadle-operated, vertically-movable plunger over the head 8 of which said mechanism is longitudinally adjustable together with the toe rest by a hand wheel 10 toward and from the heel post for lasts of diflerent lengths. The toe lasting mechanism includes lasting plates or wipers 12 which are actuated to do their work by the usual connections with a horizontally swinging hand lever 14. The heel lasting mechanism includes lasting plates or wipers 16 operatively connected with the horizontally swinging lever 18 and also includes a heel embracing band 20 operatively connected with mechanism controlled or operated by the treadle 22. The toe lasting devices are supported upon a plate 24 which is connected by a vertical pivot 25 with the intermediate plate 26 which is adjusted as above described by a Of course this invention will be readilyv distinguished from machines such as those.

screw and hand wheel 10 longitudinally over the head 8 of the vertically movable plunger. The front end of the plate 24 is curved about the pivot 25 as a center and has a lip over which lies a gib 28 on the plate 26 for holding down and guiding the plate 24. The pivot 25 is located in the median line of the machine at a substantial distance in front of the toe lasting plates or wipers and the adjacent end of the last.

The heel lasting mechanism is supported upon a carrier 30 which is pivotally connected to the frame at 35, which is a point located in the median line of the machine,

under the last, and at a substantial distance forwardly from the heel end of the "last, and preferably substantially under the location of the breast line for the shoe heel. The rear end of the plate 30 is curved about the center 35 and has a lip over which hangs a gib or guiding flange 36 on the frame.

The plate 24 of the toe lasting head has a lateral projection at the rear side of "the machine which carries a roll or stud standing in a slot in the head 38 of a bar 40, said slot permitting adjustment of the heel lasting head longitudinally without moving the bar 40. The stem of the bar 40 slides freely in guideways formed in a bracket 42 attached to the machine frame, this movement accompanying and being effected by adjustment of the heel lasting devices about the center 85. The bar 40 rigidly supports between its hearings in the bracket 42 a block 45 which has an adjustable connection with the angular end of a lever 46 being fastened in adjusted position by a binding bolt 43. This lever is fulcrumed on the bracket at 47 and its long arm is pivoted at 48 to a link 50 which is pivoted to a block 52 attached to the side of the carrier 30 upon which the heel lasting devices are mounted for lateral curvilinear movement about the pivot 35. The block 52 is adjustable lengthwise of the machine by the screw 54.

By means of the connection 46, 50 between the toe lasting mechanism and the heel lasting mechanism the two mechanisms are adjusted together or by single adjusting movements, as, for example, by force applied laterally by the hand of the operator to the toe lasting mechanism or the heel lasting mechanism. Also, this connection combined with the location of the pivots 25 and 35 effects movement of *the toe lasting mechanism laterally toward one side of the machine and effects movement of the heel lasting mechanism toward the opposite side of the machine. The screw 54 provides means for adjusting the connection between the heel lasting mechanism and the link 50 toward and from the pivot 35 whereby a given lateral movement of the toe lasting mechanism will eifect a variable movement of the heel lasting mechanism.

In the use of the machine a shoe will be applied to the supporting devices in the usual way, the lasting mechanism will then be adjusted as, for example, by pushing the toe lasting devices toward the right hand or back side of the machine, as indicated in Fig. 3 for a left shoe, until said devices are positioned symmetrically with relation to the toe end of the shoe. the toe lasting mechanism is accompanied by a lateral curvilinear movement of the toe rest which is attached thereto and to the shoe which is supported at its toe end on said rest. companied by a lateral curvilinear movement of the heel lasting mechanism in the opposite direction or toward the left in Fig.

3. If the block 52 has been'properly adjusted for the style of shoe' that is to be lasted, this adjustment of the heel lasting mechanism thus effected will position that mechanism symmetrically with relation to the heel portion of the shoe. This adjust ment of the block 52 having once been found for a style of last may remain constant un til a different style or shape of last is presented. If the adjustment of the heel lasting mechanism is not correct when the toe lasting mechanism has been adjusted into symmetrical relation to the forepart of a last, additional adjustment for the heel lasting mechanism may be efiected by manipulation of the screw 54. The links 46 and 50 constitute a sort of toggle.
